Dual 8" 1000W Peak Dual 2 Ohm Vented Subwoofer Enclosure with Amplifier

Dual 8" Subwoofers: Pre-installed in a vented enclosure for precise and powerful bass Power Handling: 1000W RMS, 2000W max for high-performance sound output Durable Build: Features corner bracing, dual baffle, and airflow-optimized slot ports to reduce flex and maximize performance Compact Design: Fits the entire width of most vehicle trunks with angled back for enhanced internal volume and stability Impedance: Dual 2 Ohm voice coils, compatible with 1-ohm or 4-ohm amplifier setups B2 Audio Dual 8" 1000W RMS 2 Ohm Vented Loaded Subwoofer Enclosure DVPE28 This listing includes: (1) Vented Loaded Dual 8" B2 Audio Enclosure (1) MICRO Series 1-Ohm 1000W Monoblock Amplifier The DVPE28 is more than loaded prefab enclosures. Features like bracing, acoustilux, airflow optimization, and L and J-shaped slot ports, along with a dual baffle, are usually reserved for custom-built enclosures. However, the DVPE incorporates all of the above and comes with dual 8â woofers, ready to satisfy any bass cravings. DUAL SUB PORTED ENCLOSURES DVPE 28 / DVPE 212 goes beyond what you can expect from a prefab. They offer a wider frequency response and a tuning frequency that makes sense so you can enjoy your music without limitations. This is also reflected in the size of the enclosures. The DVPEs are made to fit, utilizing the entire width of most vehicleâs trunk space, and having an angled back to increase the inner volume. All of this helps achieve more bass with less power. CORNERS & ANGLES NO FLEX should be a fundamental consideration when constructing enclosures. Regrettably, many enclosures do not match their external appearance internally. The presence of flex can significantly impact both performance and overall quality. The DVPE features corner bracing, full-height slot ports (which also act as bracing), and a wedged design to enhance stability. With a tuning of 40 Hz, one would typically require longer ports or a larger enclosure. However, in our case, the ports are designed with 3 90-degree bends, each featuring an angled/rounded curve to optimize airflow and maximize the performance of these enclosures. The 2 x 8 or 2 x 12 configurations can be connected in either a 1-ohm or 4-ohm load, allowing them to be compatible with amplifiers of varying sizes.
